A random flight chain model for the tether of the Shaker K+ channel inactivation domain.

Abstract

Rapid inactivation of Shaker K+ channels occurs when a domain in the amino terminal region of the channel protein blocks the pore. Some part of the sequence between the inactivating domain and the first transmembrane segment may form a flexible tether. We consider the possibility that the tether has no secondary structure, but is rather a polypeptide random… (More)
